I recall, in earlier incarnations of Windows, I used to use Net Vampire to help me download files, and I could usually resume downloading a file if
the connection wasn't great.

I've been trying to download Open Office onto my Windows 8.1 machine, and it seems to stop load with only part of the file. I've tried a second
time, with no luck.

I have looked at what seems to be happening with Total Commander. The first time, I had a listing for the .exe file listed at a size of 0, and
another file of the same name with an extension .part (so it seems to be, anyway). I've had downloads look like this, before, but the .part file
would keep getting larger each time I checked, until it was full size. This seems not to continue to grow.
